public class WebcamClass {

CaptureDeviceInfo cam;
MediaLocator locator;
Player player;
FormatControl formatControl;

public static void main ( String args [] ){
    WebcamClass camera = new WebcamClass();   
   
}

public WebcamClass(){

    try{
                    // List out available Devices to Capture Video.
        CaptureDeviceManager manager = new CaptureDeviceManager();
        //System.out.println("List device : " + manager.toString());
        
        Vector<capturedeviceinfo> list = manager.getDeviceList (null);
        
        System.out.println("List device : " + list.toString());
        
        for(CaptureDeviceInfo temp : list){
            // Checking whether the current device supports VfW
            // VfW = Video for Windows
                        if(temp.getName().startsWith("vfw:"))
                        {
            System.out.println("Found : "+temp.getName().substring(4));
            // Selecting the very first device that supports VfW
            cam = temp;
            System.out.println("Selected : "+cam.getName().substring(4));
            break;
                        }
        }

        System.out.println("Put it on work!...");
        
        // Getting the MediaLocator for Selected device.
        // MediaLocator describes the location of media content
        //locator = cam.getLocator();
        String source = "vfw://0";
        //source = "";
        locator = new MediaLocator(source);
        if(locator != null){
System.out.println("locate :" + locator.toString());
            // Create a Player for Media Located by MediaLocator
            player = Manager.createRealizedPlayer(locator);

            if(player != null){

                // Starting the player
                player.start();

                // Creating a Frame to display Video
                JFrame f = new JFrame();
                f.setTitle("Display Webcam");

                f.setLayout(new BorderLayout());
                // Adding the Visual Component to display Video captured by Player
                // from URL provided by MediaLocator
                f.add(player.getVisualComponent(), BorderLayout.CENTER);
                f.pack();
                f.setVisible(true);
            }

        }

    }catch(Exception e){
        System.out.println(e);

推荐答案

我不知道您要在那里尝试-但这不是applet.

请遵循:
Applet教程 [

I don''t know what you ae trying there - but that''s no applet.

Follow this:
Applet Tutorial[^]

To get a valid applet. Also needs the browser to accept the Java Applet.
If that support is disabled by default, you might never notice the applet is there.
